Activist investors have sent shockwaves through corporations in recent years, personally targeting directors and executives at some of the world's largest companies. No longer satisfied with operating on the fringes of business, they are now a firm fixture in the boardroom.

Up to a quarter of public companies could be targeted by activist campaigns in the coming years, with directors and executives at those corporations threatened with losing their jobs. The trend, which began in corporate America, has spread to the UK, Europe and Asia, taking in several high profile companies.

Barbarians in the Boardroom tells a compelling story of boardroom bust ups, dumped CEOs triumphant activists and pared back companies. It reveals real-life examples and interviews with executives and investors to explain why and how activist investors have managed to storm Wall Street and tear down City citadels. Owen Walker provides an insight into the way activists think, how they decide to target a company and how directors and executives could possibly work with them rather than against them.
